REUTERS/Aly Song/File Photo Acquire Licensing RightsNov 28 (Reuters) - Micron Technology (MU.O) expects first-quarter operating expenses to be higher than its prior estimates, sending the memory chipmaker's shares down 3%, even as the company projected revenue to trend towards the upper-limit of its forecast. The company on Tuesday estimated adjusted operating expenses of about $990 million in the quarter ending Nov. 30, higher that its prior expectation of $900 million, plus or minus $15 million. The higher expenses are driven by the timing of R&D costs as well as asset sales, CEO Sanjay Mehrotra said at the UBS Global Technology Conference on Tuesday. Micron said it now expects revenue to approach $4.7 billion, compared with its previous estimate of $4.4 billion, plus or minus $200 million. It previously forecast loss of $1.07 per share, plus or minus 7 cents.
